WRAPQPING- MECHANISM FOR CANDY.

Specification of Letters Patent.

Patented J an. 27, 1920.

Application filed July 6, 1918. Serial No. 243,604.

To all 'whom it ma concern:

Be it known t at we, MILFonD B. FER- GUSON and EDWARD HAAs, citizens of the United States, and residents of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a. new and Improved Vrapping Mechanism for Candy, 0f which the following is a full, clear, and exact description.

Our invention relates to wrapping mechanisms for candies, particularly designed for wrapping cylindrical or prismaticallyshaped candies.

An object of the invention is to provide a simple and efiicient mechanism with which candies can be quickly and neatly wrapped.

Another object of the invention is to provide a candy-wrapping mechanism which can form part of a machine for labeling, packing and otherwise manipulating candies after they have been wrapped.

vWith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in al l the views.

Figure 1 is a diagrammatic side elevation of the wrapping mechanism;

Fig. 2 is a similar fragmentary elevation of the mechanism showing a different position of the candy feed and paper cutting elements;

Fig. is a similar elevation to that shown in Fig. 1 with a further change in position of the various elements of the mechanism;

Fig. 4 is a top plan view of the mechanism as shown in Fig. 3, certain parts being shown in section to illustrate the details or' construction Fig. 5 is an elevation of the spinning mechanism and the means for actuating the same; y

Fig. G is a section through the mechanism on line 6 6, Fig. 5;

Fig. 7 is a diagrammatic elevation of the spinning mechanism and track, the spinning mechanism being shown in a raised position;

Fig. 8 is a similar View showing the spinning mechanism in operative position; and

Fig. 9 shows an end elevation of the candy with the wrapping paper about the candy after the spinning mechanism is disengaged from the candy.

Referring to the drawings, particularly to Fig. 1, 10 is the paper roll supported to revolve on a suitable core 11, the bearings for which are not shown. The paper from the roll is guided through feeding pressure rolls 12, both of which rolls receives an intermittent rotary movement in one direction only through a ratchet and gear mechanism 18 actuated from a crank pin 14. This arrangement, therefore, will intermittently advance a predetermined length of the paper through a shearing device 15 through which the paper is fed after it has passed the' feeding rolls 12. The shearing device is operable intermittently by a face cam 16 (see Fig. 2). The cam 16 and the gear mechanism 18 are so synchronized that the shears will operate when the feeding of paper through the rolls is interrupted.

The shearing device 15 is supported to bring the end of the paper between the free end of an arm 17 and a track 18. The free end 19 of the arm 17 is enlarged to Ia width substantially equal to the width of the candy. This end carries wires 19 extending toward the track and which form a support for the end of the paper fed in front of the track 18. A platform 20 alines with the top of the end 19 of the arm 17. This end supports the candy 22 while the same is moved into the track. The platform 20 alines with the conveyer 21 which brings the candy on the platform.

The platform 20 alines alsowith the stationary bottom 23 of the track 18. The top of the track is made in yielding sections 24 and 25. The section 24 has a raised portion 26 between the ends adapted to form a bearing for candies 22 when the same are forced into the track by a push bar 27. The push bar is supported in front of the platform 2O on a standard 28 which is slidably mounted on a stationary guide 29 of the mechanism. The standard ,28 is connected by a rod 30 to a slide 31 which carries a fork 32 for advancing or removing the wrapped candies from the track to the Wheel 33 which coperates with the gumming device, not shown. The slide 31 is supported by a movable guide 34 which is raised and lowered by means of bell cranks 35 connected by a bar 36, the bell cranks being actuated from a ed cam 37, the slide 31 being also .actuated from a grooved cam 38 through the medium of bell cranks 39 connected by a rod 40. The two grooved cams 37 and 38 are synchroniaed,v so that while the slide is in operation the guide is stationary, and vice versa.

The standard 28 being connected to the slide 31 is therefore operable when the slide is o erated. The upward movement of the ui'e and therefore of the slide therewith oes not produce any appreciable movement ofthe standard 28 and therefore of the push bar 27. This upward movement of the guide brings the fork 32 above the bottom 23 of the track (see Fig. 8). The slide 31 is then pulled rearwardly carryin therewith the push bar which will shove t e candies 22 on the platform 20, while the fork will move the candies in the track and out of same, as indicated in dotted lines in Fig. 3. The arm 17 has an extension 41 which rests on a roller 42 carried by the bed of the standard and on which the extension 41 is adapted to ride. The extension has an incline 43 which is adapted to be engaged by the roller 42 when the standard is moved rearwardly with the slide, as previously stated. In consequence the arm 17 is swung toward the roller 18 as the push bar moves toward the candies 22.

The incline 43 is so related to the roller 42 that the same begins to engage the ineline at the moment the push bar 27 brings the candies 22 on to the end 19 of the arm 17; therefore, the candies. arm and push bar move in unison. the lever supporting the candies in the gap. The incline 43 is Sulliciently long to bring the arm to the track and maintain it ther-eat while the push bar moves the candies 22 into the bearing 26 of the track. Since the end of the wrapping paper is located between the end of the arm 7 and track 18. the paper will be engaged by the candy in its movement into the track. The shearing device severs a sect-ion of the wrapping paper when the candy enters the track. therefore. the candy 22 enters the track 18 with the wrapping paper. In consequence, the paper is folded by the track about the candy moved thereinto. the vielding section 24 of the track causing suilieient friction between the paper and the track to cause the paper to be dragged out from between the roller 18 and the end 19 of the arm (see Fig. T) and push it with the candy7 until the bearing in the track is reached. In

the guiding` pulleys 52.

consequence, the wrapping paper is folded about the candy near to one end of said wrapping paper.

The shorter end of the wrapping paper is then tucked or folded against the candy by fingers 44 mounted at one end of .1 lever 45 which is pivoted between the ends. and the other end of which lever is actuated by a cam 46. The lingers 44 complement the bearing formed by the raised portion 26 in the upper section of the track 24 in which the candy with the paper folded about it can be rotated or spun by means of a pair of endless belts 47 provided above and bclow the track. The cam 46 is timed so as to swing the lever 45 to bring the fingers ll against the candy brought into the bearing 26 of the track after the push bar 27 begins to retract.

Endless belts are driven by pulleys 48 each constrained to revolve with a shaft 49. Each shaft bears in a corresponding sleeve 50 (see Figs. 4. 5 and 6). Each sleeve has an arm 51 adjacent the pulley extending along the endless belt and carrying at the free end a guiding pulley 52 for the endless belt. The other end of each sleeve carries a head 53. the two heads having interengaging toothed sections 54 the purpose of which will appear hereinafter. The sleeves are supported in the frame structure 55 of the mechanism.

The oscillation of the sleeves 5l) in their bearing is controlled by a groove cam 56 which actuates a lever 57 pivoted between its ends and which is in turn connected b v a link 57 to one of the heads 53. The bottom 23 and the section of the track are cut out to allow the endless belts to protrude therethrough to come into engagement with the candies 22 in the track. To increase the contact between the belts and the candies we provide an idler 58 within each belt. between the driving pulleys 48 and The bolts arc` rotated intermittently from a toothed sector 59 which meshes with a gear 6() rcvolublv mounted on one of the shafts 49. The same shaft carries a ratchet 61 constrained to revolve with the shaft and which is engaged b v a spring-actuated pawl 62 carried by a plate 63 which is rigid with the gear 60. Each of the shafts 49 carries a pinion 64 constrained to revolve with the corresponding shaft. the two pinions being geared b v an idler pinion 65.

The sector 59 is oscillated through the medium of a rod 66 which engages a groove cam 67. The pawl and ratchet mechanism will transmit the oscillating motion of the sector into the intermittent rotary motion of the shafts and. therefore. of the driving pulleys 48, as indicated b v the arrows in Fig. 8.

The cani 56 is so timed as to move the two arms 50 toward one another to grip the candy therebetween before the cam i6 has brought the fingers 44 against the candy in the track. The movement of the arms by the cam 56 brings the belts through the cutouts in the track against the candy supported by the bearing fori ied in the track and the lingers 44. This engagement of the Jelts with the candy is maintained so by the cam 56 until the candy has been spun or revolved on its axis by the belts il' by the oscillation of the sector 59. the motion of which is timed by the cani 67.

The displacement of the belts 47 is only suiiicient to wrap the caiidy in the paper by leaving one end of the paper so that the saine could be pasted subsequently. Before the guide Si 'is raised the cani 56 parts the arms 50 and tlierebv releases the grip of the belts on the candy and leaves the candy wrapped with the paper under the pressure of the yielding section 24. After the guide has been raised to bring the fork 3:2 to the candy in the track, the cam 38 actuates the slide 3i and moves the wrapped candv from the section 2e to the section 25 (see Fig. 3), and the candy that was in section 25 is moved out of the track to the wheel 33. It will be noted that the unwindiiig of the paper is prevented by the frictional engagement of the track with the candy that is shoved in the track.

Vfhile the disclosure refers to the wrapping of candy, it is self-evident that the inachine can be employed for wrapping any articles of approximately cylindrical form and. therefore, we do not wish to be limited to the wrapping of candy only.
